Default washboard feeling on shift from 3-4th

Right at about 47kmh, during the shift from 3rd to 4th, it feels like I'm driving over washboard. Is this the "thump" I keep hearing about?

(It showed up less than 2 days after the end of warrany)

Check your spark plugs.

Default Thanks

I will do that. The timing belt was just done, so I thought maybe that could be the cause.
I also let the oil level get to the point that the light came on...
I like the idea that it's just the spark plugs though.

Default I had a shudder at low speeds, at around 1200 to 1400 rpms.

It was from fourth to fifth. I thought it was my transmission, it felt like a washboard feeling.

It was my spark plugs. I did not torqued them correctly due to torque wrench failure and the gases ventilated through the plug hole causing heat and deteriorating the plugs.

Bad or excesively worn plugs can cause the vehicle to shudder at low rps under load (fourth to fifth gear).<ul><li><a href="https://forums.audiworld.com/a8/msgs/164731.phtml">https://forums.audiworld.com/a8/msgs/164731.phtml</a</li></ul>
